A student is preparing a presentation on the history of superconductivity and has taken the following notes:
* In , Dutch physicist Heike Kamerlingh Onnes discovered superconductivity.
* Superconductivity is the complete absence of electrical resistance in certain materials.
* Onnes first observed this phenomenon while cooling solid mercury to a temperature of Kelvin.
* For his pioneering low-temperature research, Onnes was awarded the Nobel Prize in Physics in .
The student wants to write a sentence that emphasizes the year superconductivity was discovered and the temperature at which it was first observed. Complete the student's statement by filling in the blanks.
Answer:First observed when mercury was cooled to 【4.2 Kelvin】, superconductivity was discovered in 【1911】.
Answer
First observed when mercury was cooled to 4.2 Kelvin, superconductivity was discovered in 1911.
The correct response completes the sentence by identifying '4.2 Kelvin' as the temperature at which the phenomenon was first observed, and '1911' as the year superconductivity was discovered, directly fulfilling the rhetorical goal.
